Application filed August 20, 1912. Serial No. 716,088.

To all whom it may concern:

Be it known that I, GEORGE W. PENNE BAKER, a citizen of the United States, residing at Albany, in the county of Linn and State of Oregon, 'have invented a new and useful Display Device, of which the following is a specification.

The present invention relates to improve ments in display devices, the primary object of the invention being the provision of a novel construction of step-by-step rotating exhibition drum operably connected to a pen depressed pen guiding spout of an ink well and so arranged as to be actuated a step at a time each insertion of the pen within the well.

A further object of the present invention is the provision of a novel form of mechanism for imparting a step-by-step move-- ment to a rotating exhibiting drum to insure.

the positive movement thereof and at the same time limit such movement to the desired degree.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-Figure 1 is a perspective view of the complete display device.

Fig. 2 is a sectional view through the drum' casing, showing the step-by-step device in elevation and in operable relation with an ink well. Fig. 3 is a section taken on line 33 of Fig. 2, looking toward the front of the casing.

Referring to the drawings, the numeral 1' designates the base, a support for the ink well 2 of conventional construction and provided with the plunger guiding tube 3, also of usual construction, said plunger being so constructed as to be depressed when the pen is introduced into the well 2 and to automatically rise when released. This plunger or guiding tube 13 is resiliently supported as is the usual custom in ink wells of this character, the resilient support having a normal tension to elevate the tube and consequently as will presently appear automatically return the actuating lever of the display drum for the next step or movement.

The casing 4 is preferably made of metal and suitably ornamented and is carried by the base 1, the rear of said casing being closed by means of a cover or door 5 hinged at 6, a lock 7 being provided to lock the same 1n closed position. A. handle 8 is provided to permit of the ready removal or transpor tation of the device. In the front wall of the casing is provided the sight aperture9 which is provided as usual with the dust excluding and transparent closure. Adjustably mounted in the respective end walls of the casing, are the j ournaling screws 10 and 10, to fit upon the opposite ends of the shaft 11, which carries the exhibit carrying drum 12, said drum being of such a size as to be readily insertible into the opening of the casing controlled by the door 5. By this means the advertisements displayed upon the drum may be readily changed when necessary. Keyed upon the shaft 11 to one side of the drum 12 is a toothed ratchet wheel 13, while projecting from the same side of the drum are a plurality of equidistantly spaced pins 14:, said pins constituting a means for preventing the too far rotation of the exhibiting drum and also areventing a retrograde movement thereo as will presently appear.

The apertured lugs 15 constitute a fulcruming means for the lever 16, which is projected through the casing 4L and is connected at 17 to the clamping ring 18 which surrounds and is secured to the vertically slidable tube 3 of the ink well 2. By this means when a pen is introduced into the tube 3 and such tube is depressed, the outer end of the lever 16 will also be depressed, elevating the inner end to actuate the exhibiting drum 12 as will presently appear. Pivoted at 19 and carried upon the inner end of the lever 16 within the casing 4 is the gravity held pawl or detent 20 whose hooked end 21 is disposed to engage at each.

elevation of the free end of the lever 16, due

to the depression of the tube 3, one tooth of the ratchet 13 and thus impart to the drum 12 a slight rotation, the arm 22 carried by the free end of the lever 16 and projecting upwardly being disposed at such times to be placed in the path of one of the pins 14 so that the pin will engage the arm 22 and thus limit the distance of rotation of the drum 12 so that each depression of the lever 16 will cause the drum 12 to move the distance from one pin 14. to the next pin 14;, the

drum rotating in the direction of the arrow as shown in Fig. 2. In order to prevent the drum 12 from rotating in the opposite clireetion to the arrow, a spring arm 23 is dis posed to engage one of the pins 14, as shown in Fig. 2 but is of a resilient material so as not to interfere with the rotation of the drum in the direction of the arrow when propelled by the lever 16.

From the foregoing description, taken in connection with the drawings it is evident that at each depression of the tube 3 due to the introduction of a pen within thewell-2, that the outer end of the lever 16 will be depressed, elevating the inner end carrying the pawl 20 and the arm 22, such elevating movement rotating the drum and at the same time placing the arm 22 in the path-of to engage one of the pins lt and thus limit the rotation of the drum 12 so that a step by-step movement is imparted to the drum 12 at each depression and elevation of the tube engaging outer end of the lever 16.

hat is claimed is The combination with a base, an in]: well mounted thereon,and a resiliently elevated reciprocatory pen receiving tube carried by the well, of a display device actuated by the tube due to the introduction and removal of a pen from the same, including a casing mounted upon the base, a drum mounted for rotation within the casing, a toothed ratchet wheel carried by the drum, a plurality of pins also carried by the drum and disposed concentrically to the axis of the drum, a lever pivoted intermediate of its ends in the forward wall of the casing and having its outer end operably connected to the tube of the ink well, whereby the lever is oscillated due to the rise and fall of the tube, a swingingly mounted hooked pawl pivoted upon the lever within the casing and in operable relation to engage the ratchet wheel as the tube of the ink well is depressed, and a pin carried by the extreme inner end of the lever and at right angles thereto for engagement with a pin to limit the rotation of the display drum during the depression of the tube.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
